Download History: Auditory Brainstem Response (ABR) testing was conducted

History:
Auditory Brainstem Response (ABR) testing was conducted today on XXXX. XXXX was accompanied by his parents who provided the case history.
XXXX has had a history of ear infections and had tubes in both ears previously though Mom reported that the tubes were now out. Recent concerns
included XXXX not responding consistently to his name, balance issues and a regression in speech to 'baby talk'. Other medical and familial history was
unremarkable with regards to hearing. Observation and interaction with XXXX today indicated age appropriate speech and language development.
Equipment: Vivosonic
Location: Rapid Treatment Unit under sedation
Referral: Dr. XXXX
All ABR trhesolds are reported with correction factors applied.
Click ABR Results (1500-4000 Hz):
Right: 20 dB eHL Interpeak interval (Wave I- Wave V) is within two standard deviations of the norm.
Left: 20 dB eHL Interpeak interval (Wave I- Wave V) is within two standard deviations of the norm.
Frequency Specific ABR testing:
500 Hz Right: 40 dB eHL Left: 30 dB eHL
1000 Hz Right: 40 dB eHL Left: 40 dB eHL
2000 Hz Right: DNT dB eHL Left: 20 dB eHL
4000 Hz Right: 20 dB eHL Left: 20 dB eHL
Bone Conduction Click (500-1300 Hz):
Unmasked Right: DNT Left: 25 dB eHL
Distortion Product Otoacoustic Emission Testing: Right: refer Test ID#5719 Left: pass Test ID#5719
Tympanometry- 226 Hz
Right: Flat: ECV 0.52cc
Left: Large Volume: ECV 2.42cc
Summary: ABR results today are consistent with a mild, low frequency hearing loss in both ears that appears conductive in nature. Otoacoustic emission
testing suggests adequate cochlear (outer hair cell) function in the left ear and results for the right ear could not rule out a hearing loss at this time.
Tympanometry results are consistent with possible middle ear fluid in the right ear and a patent ventilating tube or perforation in the left ear though
neither could be visualized.
Impressions/Parental Education: Today's results and recommendations were verbally discussed with XXXX’s parents. They demonstrated
understanding by asking appropriate questions and summarizing results.
Recommendations:
Medical consultation for middle ear evaluation then repeat hearing testing upon middle ear clearance. XXXX should be able to complete behavioral
testing. Parents were given locations available for follow up testing.
Thank you for allowing me to participate in the care of XXXX. If there are any questions about test results or recommendations, please call 801-XXXXXXX.
